The previous fix (container IP resolution) still failed because the
CI runner and compose containers are on separate Docker networks.
- Add docker-compose.ci.yml override with network_mode: host so the
container shares the runner's network stack directly
- Add --connect-timeout 2 to curl in wait-for-healthy.sh so it fails
fast instead of hanging indefinitely on unreachable hosts
- Cap health check at 30s (server boots in 5-10s)
